Playability:
Simple maze game but it seems none of the walls block movement. Keep working on this and try implementing different methods of collision to see which fits best!
Theme:
There is a light narrative here that hints at the theme but the gameplay doesn't really showcase this much.
Cleverness:
Good job working on your first game you made the circle move! Keep making things and don't stop here!
Artistic Style:
Simple and consistent programmer art. Takes time to make something else and there is nothing wrong with having simple assets.
